New Jersey Gov. Chris Christie continued to question whether Marco Rubio has the experience to be president during the Republican presidential debate in Manchester, N.H. Saturday.

"You have not been involved in a consequential decision you had to be held accountable. You just simply haven't," Christie said. "None of that stuff happens on the floor of the United States Senate ... It's a fine job, I'm glad you ran for it but it does not prepare you for president of the United States."

Rubio tried to fight back against the attack three different times, with basically the same line.

"Let's dispel, once and for all with this fiction that ... Barack Obama doesn't know what he's doing," Rubio said. "This notion that Barack Obama doesn't know what he's doing is just not true."
